Improvement; iii- Yokes f r 'Draft-Gears, of which:v helfollowing; is aspecilieat onlf v This invention relates in; general to yok'es for drafbgears and has: for its ob]ect broadly the provision of a yoke for a drawlower plates and attendant parts can be separately :removed, withopt remov ng the yoke: from the draft -rigging and w thout theuse of saeks'or. other augzdlary supports. A further object of the invent on is the provision of a structure of this eharacter in which the draw-bar may be positioned by as son of the;- draw bar afterithe installation of th yoke: in the draft;gear is. complete.

At. tilljpflherob ct lof the im'ention is the provision -of such a structure in which the 1,-draW-bar when secured "will eng age 0 a lllfoun sides.

Other. objects a vention will-beapparent as-it isbetter understood from the following description when considered in-. connectionwith the accompanying drawing illustrating a preferred embodiment thereon,

' For the purpose 1 of illustrating my invention I have shown on the drawing ayoke generally designated ataA in) a which is, 8.6-,

'limb 11 being stationary when the yoke is secured in a draft-gear and the limb 12 having movement with respect-to the limb 11in scribed.

head '14:, the tail 13 serving to connect the limb 12 with the limb 11 and the head 14 to retain it in the spaced relation required to provide the channel or space for the fol-'1 lower plates. The head 14;, which is formed J on the forward end of the limb 11,-i's adapted to receive the butt B of the draw-bar from thefront. The draw-bar anddts'but-t are of ordinary standard construction, the

butt being larger than the shank :15 which connects 1t with the coupler head 16. .This arrangement provides a pair of oppositely disposed shoulders 17 and 18 at the-top and bottom of the, butt.

Between the shoulders 17 and 18 an .aperture 19 is provided for the reception of a. key 21. In accordance with my invention it is intended that the butt with the keyin place shall be inserted through the forward face or wall of the head 14 of theyloke-"and' .7 after insertion be lifted to bring the ldLELWr-if.

ways are offset, as will be seen from Fig. .1, so that after the butt enters the-yokehead is provided at its front with a downwardly 100 extending shoulder 27 behind which the upper shou den 17 of the butt of the draw-barengages. The lower shoulder 18 engages behind a shoulder 28 formed, for the purpose at the-forward end of the limb 12. This 106 shoulder lifts the draw-bar from-itspos-l- 'tion immediately after insertion into the yoke head {ilito final operative position through a In .e'mentacrossthe yoke. The

limb Z12 'carrlesiat its-rear end a hook- 29 110 at a plurality of directions, as will be laterde- The limb 11 carries a tail 13 and a 9 0 verticalwall of the' yoke head; Theseaguide- These ofi'set ortionsprov-ide shoulhaving rounded tinder surfaces which en gage over the top of a wall 32 the side or which is eoneave, as seen at to give; a

double pivotal nmvement to the limb 12,,

one at such pivotal i'novements permitting swinging of the limb across the yoke'and the other permitting it to drop down vertically under certain conditions, When the butt of the draw-bar is inserted the limb 12 is dis iios'ed in the position shown in full lines in Fig. 1. That lf tu say, it is strong trai'isrersely witli respm-t' to the yoke to dis-- 281-0 one side to permit pose the shoulderel'itrance of the draw-liar butt. The shoulder 28 extends upwardly itrom the limb l2 and a second shoulder extends down wardlyi The lower .l'aee of this shmi'ider is beveled at 36 and rides llipon a berrlell surface 37 provided on the tioor or upper :faeeof the bottom wall 3b of the yoke'head. VVhc-n one-beveled lace slides over the other thedrmv-bar will. be lifted and engagement formed between the tlltt\\'-l.ltll and the yoke from the draft-gearand 18 of the draw-bin: butt.

i ate-all four walls of the yokehead the two eiigagement with a cotter pin in parts against. any relative movement.

It will be manifest iron: the foregoing that tho 'di*awbar may bereadily removed and positioned without removing the yoke merely by taking out shifting the limb 125 the cotter pin 4H5 and lines in Fig-1'1.

to the side, as shown in fall \Vhen, however, 'itis follower plates and the-spring and other atteiida nt parts, the cotter pin in and bolt 39 are removed and thelniovalile end of the.

head, when-it; may be lowered through its vertical pivotal movement, 1.

down out of the way, i

From the foregoing it will be seen that ti1e.;1'riov:il'ile end oi. the limb 12 has two separate- .lllil'Yflll-ltlltfi one to the side to permit; reint'ival of the. draw-ha and the other dowi warllly from said side movement; to permit removal of the follower plates, and associated. parts andn'ieclianism.

not cause removal (ifs-the draw-'bnr,the drawbar niei'ely'drop nng down somewhat 'nizisegzea to hold the desired to remove the .5. dropped Wherr properly constructed, the movement of the limb 12 to take out the follower plates will 7 as the shoulder 28 is removed, but not sulfieiently to permit itto fall out of the yoke.

The ends 22 of the key are inclosed wholly within the head of the yoke, although they need not be, and if desired the key may be madeintegral with the draw-bar. In the uresentinstance the rear part of the key is cut away at Site give the draw-bar the desired travel in bufiin It is thought that the invention and many oi? its attendant advantages will be understood from the foregoing description, and it will. be apparent that various changes may be made in the form, construction and arrangement of the parts without departing from the spirit and scope ot'the invention or sacrificing any of its material advantages, the form l'lQl'GllllJBllUl'B described being merely a preferred embodiment thereof.
